4. Using the Phillips screwdriver, loosen the screw that holds the solenoid
valve electrical connector in place, and then remove the connector from
the valve.
5. Using the 9/16-inch wrench, loosen the fitting nuts and disconnect the
lines for the FTIR In, FTIR Out, Ejector Air In, and Ejector Air
Exhaust. The 5/8-inch wrench may be used to keep the bulkhead nuts
against the sample system heater assembly from turning (for FTIR In
and FTIR Out).Note the location of each line to facilitate
reconnection. To fully disconnect the Ejector Exhaust (which has rigid
plumbing), use the Phillips screwdriver to loosen the 2 slide plate
screws on either side of the heater assembly box, just enough to slide
the box to the right to disengage it from the tubing.
6. Disconnect the sample system heaters from the rear of the temperature
control box by removing the twist lock connector from the position
labeled "Pump". Turn the connector nut counterclockwise and pull it
out of its socket. Remove the cable assembly tie-wraps using the wire
cutters.
